“The show has always been about the city of New York as much as the actors. The casting is designed to keep the series fresh while honoring the legacy.”

Dick Wolf, creator (from an interview with the Television Academy)

“Joining Law & Order is a dream come true. The energy on set is electric—you can feel the history in every scene.”

Wolf’s “New York as character” philosophy means every actor stepping into the precinct understands they are inheriting a role that countless viewers already feel a deep connection to.
